50 Claims.

The present invention relates to shoe machinery and more particularly toshoe upper shapers designed to form and shape shoe uppers, and to smooththe backs and sides thereof.

No matter how carefully shoes are made, or the uppers of shoes are cut,fittedand lasted, manufacturing processes tendto produce a gaping of thequarters, wrinkling or roughness at the seams, and similar faultsdimcult to eradicate afterwards. This isparticularly true when it isconsidered that the shoe must be removed from the last. Accordingly, oneof the objects of this invention is to so shape the finished upper as toeliminate such faults, and to impart a finish to the quarters of theshoes, by smoothing out the back seams and lining, and setting up thequarters.

More particularly, the herein described invention eiects improvements inthe art by conforming and modifying shoe Shapers of the type describedin the United States patents to Ruff, et al., No. 1,334,968, of March30, 1920, and to Freeman, et al., No. 1,720,891 of July 16, 1929.

In the improved mechanism, as heretofore, there is provided a pluralityof forms and shaping members on a rotatable head or turret. ,Each of theshaping forms is provided with a heating unit, and the arrangement issuch that the shoes or upper parts may remain within the shapingmechanism a more evenly regulated time than has been obtained with theuse of a single form and shaping unit. The ecient and novel operationwith accurately controlled temperature and pressure, eliminates thepossibility of ruining the iine leather of shoe uppers by too greatexposure to heat or pressure in the shaping operation.

The forms are so designed, and arranged on the turret in such a mannerthat when a shoe 40 element is once placed on a form, it will besupported thereon in proper position for shaping without the assistanceof an operator.

The series of complementary shaping forms are movable in unison, withthe turret, such that the movement of one unit away from theA operator,brings the next unit into operating position, and the operator placingshoes on the forms need not move out of position, thereby saving timeand labor over that required to feed a plurality of individual pressingunits having no cooperating relation.

It is a further object in the improved structure 55 parts that therewill be little likelihood of damage being done to the electricalconnections inadvertently.

The electrical mechanism is preferably provided with a stationaryrheostat connected by push pin sockets to stationary brushes which arein contact with rings. through `which electric current may passtoindividual heating units in the respective shaping forms.' Thisconstruction makes a standard head or turret together with itselectrical' connections available for any desired number of shapingunits without additional changes in structure.

`A specific object of this invention is the provision of improved meansfor shaping shoe uppers on forms, cooperative with elements which 15apply localized pressures'to the mounted shoe uppers with ya constantforce, applied during a complete cycle of rotation of the turret head ofthe machine.

While machines of the type illustrated in the 20 said patents embodystructural features capable of carrying out some of the hereinrecited'objects, theyA are nevertheless essentially hand operateddevices, Whereas the instant structure is primarily a power actuatedShaper, although ca- 25 pable of ready adaptation for hand operationshould same be found-desirable. n

Among the objects of the present invention is the provision of mechanismacting as a very effective lock against displacement of movable ,30parts, shoe elements positioned on the machine, etc., during thecycleoffrevolution;

Inasmuch as the structure herein described may be used for pressing,shaping, and forming complete shoes, assembled or unassembled por- 35tions of shoes, the term shoe element is employed to include allclasses.l

An important object of the invention is the application and regulationof sufficientv pressure along the sides and backs of shoe uppers particoularly, to effect a permanent shape, together with the applicationandmaintenance of such pressure by power actuated means.

An improved clamping or pressing mechanism is provided inconjunctionwith the form upon which the vshoe is placed, consisting of vclampingmembers which may be interconnected and movable to apply pressure in aplurality of directions, e. g., longitudinally of the shoe element, andtransversely thereof from diierent sides, this mechanism, however,utilizing the same broad principle of operation as illustrated in PatentNo. 1,720,891.

Inasmuch as the thickness of leathers, seams, etc., may vary, a uniquecushioning mechanism is provided to equalize pressures applied to theopposite sides of the shoe element, such that the pressures against oneside will automatically equalize with those applied to the other side ofthe shoe without, in any manner, disturbing the pressures appliedagainst the back or heel portion of the shoe element.

While a preferred form illustrates clamping members interconnected insuch a manner that pressure may be applied along the back seams of theshoe element as well as about the sides and quarters, it is within thescope of this invention to utilize clamping and pressing memberswhichare not interconnected and in which the pressure-on the back seammay be applied independently from that applied to the sides, or may beeliminated entirely if found desirable. Such an arrangement isillustrated herein.

Mounting of an entire shaping mechanism and form, as a single unit whichmay be readily detached from the rotatable turret, is also contemplated,together with the use of selected and interchangeable units, whereby onemachine may be' adapted to accommodate different widths and sizes for arun of shoes such as womens, or for interchanging units to t the machinefor other runs of shoes such as growing girls, misses, boys, mens, etc.l Conditions may arise where it will be unnecessar'yto utilize all ofthe units on the' machine for a vgiven operation, and it is an object ofthe invention to provide means whereby mounted units may be renderedinoperative during the use of other units.

A still further object includes control means effective to permit theapplication of power to the turret, whereby to rotate the turret adistance equal to the space between any pair of presser-units, and thenautomatically cut out the power, thus' insuring adequate placement ofeach unit to the operator.

It is further contemplated that various adjusting means will beprovided, whereby individual portions of the unit, as well as the unititself, may be variably positioned to accommodate any operator. 'I'heassembled turret and associated parts are mounted for verticaladjustments to accommodate the height of an operator without any changesin either the electrical equipment or the shaping mechanism.

Although the general principle of operation is quite similar to thedisclosures of Freeman Patent No. 1,720,891, mentioned above,improvements have been made by way of variation in the structureV of theindividual presser units andin the application of power to operate theturret and the individual heads mounted thereon.

It is to be understood, however, that units of the type illustarted inthe machine of said patent, or equivalents thereof, may be utilized ifdesired, in the machine of the instant invention with but very slightadaptation, other than the substitution of one unit for the hereindescribed pressing heads. y

Referring more specifically to the drawings in which like referencenumerals designate like parts, there is generally indicated at I, acolumn formed with an enlarged base portion 2 which not only provides anadequate support for the entire machine, but serves to house most of theactuating and control mechanism.

The column being hollow, serves to house connections from the actuatingmechanism to the driven parts which are supported at the top of thecolumn.

A turret 3 has secured thereto or formed integrally therewith, a sleeve4 about which is adjustably clamped a rsplit collar 5. The sleeve 4which forms a stem or support for the turret 3, has an external diameterequal to the internal diameter ofthe upper portion of the column I. Thetop of the column provides a bearing 6 for the collar 5, whereby,through the medium of the collar the turret is rotatably supported onthe column, while at the same time, it may be vertically adjustedthereon.

A cam member 'I having a single vlow point or notch la., and acontinuous upper cam surface 8, is adjustably, but fixedly, mountedexteriorly of the column I below the turret and hence, may be positionedto engage elements carried by the turret, in any position of'adjustmentof the turret. In other words, as the turret is vertically adjustable,so also is the cam members 6.

As shown vparticularly in Figs. 1 and 2 the turret is in the form of awheel having a series of spoke-like webs 9, the outer ends of which areinterconnected for the lsake of strength and rigidity. The outer end ofeach web is formed with a boss ID having an enlarged opening II toreceive Va supporting shank of an individual pressing unit, and Vasmaller opening I2 therebelow to receivea steadying pin on such u nit,whereby the unit may be rigidly supported on the turret. An openingextending through the boss at an angle to the opening I I may serve forreception of a set screw I3 designed to clamp the head in position.

Leads I4 extend from a pin socket I5 at the linner end vof each openingII through the webs 9 to a commutatorand vconnections indicatedgenerally at I6. This commutator and the various electrical connectionsare generally the same asdisclosed in Patent No. 1,720,891, and need noparticular description here. Suffice to say, that the commutator isrelatively fixed and makes electrical contact with brushes at the endsof the leads I4 whereby current may pass to the individual heads, whileinteriorly mounted are pin and socket connections I1--I 8 for detachablyconnecting a rheostat organization, which may be positioned iiatwiseover the upper central part of the turret. Ihis rheostat organizationand controls will be housed in a dust excluding casing I9.

The commutator is carried on a shaft 20 which extends to the base of thecolumn in non-rotatable relation to the column, but which may beadjusted vertically to accommodate adjustments of the turret. Below theboss 18 on each of the Webs 9 is a projecting lug 23 to which is pivoteda rocker arm 24 terminating at its inner end. ina tapered roller 25which is positioned to ride upon the cam surface 8 of cam member 1.

The outer end of the rocker arm 24 is pivoted at 25 to a connecting rod21. A cross head 28 is mounted for free movement on the connecting rod21 which extends through a, central hole in the cross head of slightlygreater diameter than the diameter of the rod 21. Between a washer or anenlarged head 29 on the end of the rod 21 and the cross head 28 is aspring 30, whereupon it will be obvious that a downward pull by theo-uter end of the rocker arm 24 will rst tend to compress the spring 38against the cross head, and thereafter move the cross head downwardly,the rod 21 and the spring 30 forming a cushion joint between the crosshead 28 and the rocker arm 24.

The ends of the cross head are connected to upwardly extending links 33which run to the head 34 of the pressing and shaping unit proper.

The head 34 is mounted on a stern 35 which extends slidably into a boss36 extending from a bracket arm 31. A pin and slot connection 38 (Fig.'1) serves to prevent rotation ofthe stem 35 in the boss 36. The bracketarm terminates at one end in a hollow shank 39, interiorly of which ispositioned an electric plug (not shown),

adapted to engage the socket l in the boss Ill,

when the shank is positioned in the opening Il, and secured in positionby means o-f the set screw I3 thus supporting the pressing unit in theturret. The exterior of the shank 39 may be suitably recessed or notchedfor reception of the set screw i3.

A steadying pin 48 will enter the opening I2 to prevent relativemovement between the turret and the head.

The outer end of the bracket 31 terminates in a form 43 having aninsulated outer face 44, the form being designed to enter and support ashoe element which is to be pressed and shaped, the sides of the form ofcourse, being shaped to the predetermined contour which the shoe elementwill take. Leads 45 extend from the plug in the hollow shank 39 to aheating ele-ment (not shown) internally of the form and are preventedfrom displacement away from the bracket 31 by an insulating plate 46.This arrangement of form, heating means and electrical connections issubstantially the same as in Patent No. 1,720,891, to which referencemay be made for further detailed description thereof.

From the description thus far of the pressing unit it will be evidentthat the form 43, upon which a shoe element will be supported Afor theshaping operation, is rigid with the turret and suitably heated byconnections extending from the zommutatorV to the interior of the formand that the head 34 of the'unit; while carried by the bracket 31 ismovable or slidable .with respect thereto and with respect to the form43.

, The links 33 which extend upwardly from the cross head 21- areconnected at their upper ends to pivot pins 41 mounted respectively incurved sliding member 48 ywhich move in an arcuate track 49, cut orformed in the head 34. Suitable slots 58 arei provided in the head 34for the pins 41, and a cover plate v34a is utilized to hold the slides48 in place, as Well as to exclude dirt therefrom.

Secured to `each of the sliding members 48 is a shaping or vpressingwing5I, these wings being interconnected across the upper end of the form byayflexible strap or contact liner 52 backed by a spring steel band 53extending downV across the interior faces of the wings 5|. The wings andband are shaped to conform substantially to the shape of the outer facesof the form 43.

A -pad 54 of yieldable material,` such as rubber,

is positioned intermediate the strap 52 and the band 53. Preferably,this pad will extend from the lowermost tip of 4one wing up over theform and down to the lowermost tip of the other wing, over the operatingsurfaces of both wings 5I The flexible strap or contact liner 52, whichis detachably held onthe wings by snap fasteners, or any equivalentmeans, act to secure the pad 54 in 101306. When the Vwings are actuatedtoapply pressure against the shoe element or the form,y there will be,in addition to the main application of pressure bythe wings 5I,localized pressures b-y the pad, inwardly against selected portions ofthe shoe. By varying theshape of the pad, and the shapeof the form,anydesired localized pressures may be obtained on the shoe, e.l g., on theextreme edges only of the shoe elementwith or without lesser pressuresagainst other portions of the shoe, or it may be advantageous to apply alocalized pressure over a substantial selected area of the side of theshoe, in addition to areas adjacent the upper edges.

Further, it may be desired to press one portion of the shoe element bydirect engagement with the wings, and another portion by interpositionof the pad. Thepad need not be extended from one wing to the other overthe form, but separate pads may be used for each wing.

Various modifications in the head unit will occur to those skilled inthe art, and as illustrative of variations from the preferred form abovedescribed, reference is made to Figs. 12 and 13,

The unit of Fig. 12 may omit the interconnecting portion between thewings 5|. 'Ihe head 34 may be provided with a forwardly extending bossor projection 4I which functions as a positive presser yoperating in adownward direction, and which may be provided with a contaci liner 52band a pad 54h.` The wings 5I will be provided with pads 54a and contactliners 52a. The operation of this form will be substantially the same asthat of the preferred form shown in Fig. 5 in that downward movement ofthe head 34 will rst produce a contact and application of pressureacross the back of the shoe at the top of the form, by the member 4|,and the wings 5l will thereafter come into engagement with the sides ofthe shoe element.

If desired the continuous contact liner 52 and a continuous pad 54 mightbe utilized in this modification, in exactly the same manner as in thepreferred form.

In Fig. 13 an arrangement is illustrated in which the head 34 mightreadily be stationary and an upper movable presser member 42 providedthereon. This member 42 is suitably connected to an extension of thepins 41 by any convenient anti-friction and lost motion connections andguided for vertical movement. If the head is held in a fixed position,such that the only movements of the pressing means will be obtainedthrough the element 42 and the wings 5I, then the pressures may beapplied simultaneously to the several parts of the shoe instead of apressure rst on the counter portion of the shoe followed by subsequentpressures onthe sides.

Hence, it willbe seen that each of the units is provided with a mainpressing means, i. e., the wings I, and a pressing means (pad or pads54) for localizing pressures, which may or may not form a part of themain pressing means. Such an auxiliar-y means may be adapted to almostany predetermined contour, made possible by variation in the thicknessand shape of the pad and changes in location thereof, whereby pressuremay be brought to bear on selected portions of shoe elements, additionalto direct pressures applied by the contoured surfaces of the wings andform.

In order to limit downward movement of the head 34 with respect to thebracket there is provided an adjusting` screw 55 carried by the head 34and engageable with a stop 56 on the bracket 31, this screwbeingeffective to variably limit the degree of movement permitted thehead 34.

A spring 51 surrounding the screw 55 and stop 56 serves normally tomaintain the head 34 in its upward or outer position on the bracket 31.

A stop 58 may be secured to the bracket 31 to limit upward movement ofthe head, although this upward movement is limited generally by therocker arm 24 and associated parts.

When tension is applied tothe cushion arrangement 21-30 to draw thecross head 28r downwardly, the links 33 and members 41 will rst draw thehead 34 downward until that portion of the strap 52 which interconnectsthe wings El engages a shoe element on the form thus resisting furtherdownward movement, the screw 55 and stop 5E being adjusted to regulatethe degree of pressure desired at this point. Thereafter the members 41will partake of a sliding movement in the arcuate track 49 to 'move theshaping wings A5I inwardly towardeach other and into engagement with thesides of a shoe element on the form. v

Obviously, then, a downward pressure will be attained at the back edgeof the shoe band; in fact, over as much of the heel portion of the shoeas desired, dependent upon the shape and size of the interconnectingportion of the linery 52, the pad 54 and the spring steel band 53.'

By increasing the thickness of the pad 54 and locating its operatingportions nearer to the top of the wings, all of the ldownward pressureof the assembly Vcan be exerted on the curved sides of the shoes, to theexclusion of positive pressure against the back seam of the shoe.

Should one side of the shoe befsomewhat thickerthan the other side, dueeitherto variable thicknesses in the leather or the seams, the crosshead will rock slightly on the connecting rod 21 due to the fact thatthe hole through-the cross head is slightly larger than the diameter ofthe rod 21 Vand thus the pressures applied t0 one side of the shoe willbe equalized to those applied to the other side of the shoe. In otherwords, the

wings will seek their own positions due to the relative movementpermitted by rocking of the cross'head.

Referring now particularly to Figs. l, 8, 9, and 11, wherein isdisclosed the power actuated mechanism for rotating the turret `and forinsuring proper compression of the shaping or pressing means about theform, there is illustrated an elo-ng-ated sleeve 60, which rotatably tsabout the shaft 20 and within which the shaft 20 may slide vertically.The sleeve 60, While rotatable, is not vertically movable but is,however, splined at 6I to the turret sleeve 4, thus permitting verticaladjustment of the turret and sleeve 4 with respect to the sleeve 60,without in any manner affecting unitary rotatable movement of the twosleeves 4 and 60.

Pinned to the sleeve 60 is a notched cam 62 which forms the directdriving connection between -the turret and the driving mechanism in thebase portion 2 of the column I, the notched cam 62 providing a directcontrol for limiting the degree of movement of the turret.

A motor M may be located in the base portion 2 of the column, or anysource of power such as a drive from conventional factory power, may beutilized for operating the machine. Where a motor is utilized, anadjustable bracket B may support same for beltv tightening purposes. Themotor may be connected by a belt 63 to a pulley 64, which is formed withan integral, elongated hub 65 mounted in a xed boss 66 of the baseportion 2. A similar boss 61 is located diametrically opposite the boss66, and a shaft 68 is mounted for limited sliding movement in the twobosses. The end of the shaft 68 Which passes through the boss 66 extendsfreely through the el-ongated pulley hub 65. Splined to the shaft is aworm 65, for rotation thereby, the shaft being free to slidelongitudinally of the worm. The worm is held against endwise movement bya pair of lugs 10 which are cast in the base of the column.

Pinned to the sleeve but, of course, independent of the shaft 20 is aworm Wheel 1I, positioned to mesh with the Worm 69.

A clutch plate 12, which may be of the friction type but which ispreferably of a semi-positive type, is rigidly keyed to the shaft 68,such that endwise movement of the shaft causes an engagement ordisengagement of the plate with the side face of the pulley 64. When thepulley and clutch are engaged, the shaft 68 will be caused to rotate bythe pulley 64, which is constantly rotating, thereby rotating the wormyand worm wheel to rotate the sleeve 60, the sleeve 4 and the turret 3.

Extending through the base portion 2 transversely of the shaft 68 isanother shaft 13, supported by a pair of lugs 14 formed in the baseportion 2. A yoke 1'5 is rigidly secured to this shaft, `adjacent oneend thereof, and an arm 16, terminating in a flanged toe portion 11 issecurely xed thereto adjacent its other end.

A stub shaft 19, carried in a suitable bearing on the base portion 2,supports a spring pressed treadle 80, in which is mounted a kick-olf pinEl, positioned to engage a lug 82, which forms a part of a control lever83. The control lever 83 is pivotally mounted on a shaft 84, carried byan'adjustable supporting bracket secured to the base 2.-

The control lever 83 carries a spring pressed, pivoted latch 85terminating at one end in a hook portion which is located to engage theangle shaped toe Hof the arm 1S.

Depression ofthe treadle 80, and consequent engagement of the pin 8lwith the lug 82, will move the latch downwardly and to the right (seeFig. 10), pulling the arm I6 to the right, Vand thereby rocking theshaft 13, which in turn rocks the yoke 15. The ends of the yoke engage aclutch shifting collar 86 secured tothe shaft 68, and movement of theyoke accordingly slides the shaft 68 to bring the clutch plate 12 intoengagement with the pulley 64.

As the arm 16 moves to the right under the iniluence of the latch 85,the curved underside of the latch rides over a cam finger 81 which'hasthe ei'ect of lifting the hook end of the latch away from the toe 11until, at the moment of engagement between the clutch plate and thepulley, the arm 16 is released, to return to its original position underthe influence of a spring 88. The cam finger 81 is,of course, adustableto accommodate various conditions.

In order to insure that the clutch plate maintains a connection betweenthe source of power and the driving mechanism long enough for the turretto move a distance equal to the space between two pressing units, thereis provided a second arm 89 pinned to the shaft 13, said arm terminatingin a toe portion carrying a cam roll 99, both arms 1S and 89 beingtherefore rigidly secured to the same shaft. The cam 62 is shaped with aseries of notches about its periphery, one notch for each pressing unitcarried by the turret head. When the turret is stationary, the roller 90will be positioned within a notch, but when the shaft 13 is rocked underthe iniluence of the treadle 89, the roll 90 will be withdrawn from itsnotch to ride on a high or peripheral surface portion of the cam, as thecam rotates with the sleever.

Obviously, the clutch plate cannot become disengaged from the pulley,even though the latch tlhas released the arm 13, due to the cam finger81, until such time as the cam roll 99 has reached an adjacent notch,whereby it will drop into such notch under the influence of the spring88 which, pulling the arm 1B in one direction, tends to push the arm 89in the opposite direction.

The end ofthe treadle 80 beyond its pivot shaft 19 is projected to forma cam 9|, adapted to engage'a cam roll 92 carried by the lower end of apush rod 93 which telescopes into a sleeve 94. Relative movement betweenthe rod and sleeve is limited by a pin 95 operating in a slot 96. Aspring 91 surrounding the rod 93 engages the lower end of the sleeve 94and abuts a collar 98 on therod. It follows then that depression of thetreadle 89 will compress the spring 91, thereby forcing the sleeve 94upwardly, maintaining the sleeve in such position until compression ofthe spring is relieved. Release of the treadle acts to release thecompression of the spring which is then free to push the rod 93downwardly, and through the medium of the pin 95 to positively returnthe sleeve 94 to a lower position as the pin reaches the bottom of theslot 96.

The cam 1 has its sole low point or notch 'ICL positioned at the frontof the machine, thatis atV a point facing the operator, and it is intothis notch that the roller 25 on the rocker 24 will ride when the turretcomes to rest with a pressing unit ready to receive a shoe element.

The upper end of the sleeve 94 carries a head 99 (Fig. 1) positioned toengage the arm 24 or the roller 25 when the treadle 89 is depressed,

whereupon depression of the treadle and upward movement of the rod 93will raise the end of the rocker 24 to ,lift the roller 25 out of thenotch in synchronism with movements of ,the driving mechanism, which isbeing released for operation by the Vdepression of the treadle.. Theturret will begin to rotate, carrying the roll 25 on to the highersurface 8 of the cam, thus drawing down the pressing wings andstraps.about the form and holding same in such position until the turret hasmade a com-plete revolution bringing the roll back to the notch again.Preferably, the head 99 will engage an'innerr end of the roller 25 tofacilitate the rotary movement of the rocker with respect to the head 99and the cam.

The general operation is as follows. When a pressing unit is in front ofthe operator, and the treadle in its normal position,v a roller will beresting in the notch 1a, thus positioning the head 34 in spaced relationto the form, whereby a shoe element may be placed on the form.

Depression of the treadle then'produces, first, a downward movement ofthe wings 5I and 'the interconnecting strap or liner 52 about the heelor counter portion of a shoe element which, of course, is positionedwith the toe pointing downward and the sole facing the'operator in theembodiment of the invention shown. Further movement of the treadle willcause an inward movement of the wings toward each other, downwardmovement being limited by engagement of the liner 52 with the shoeelement, and by the stop 56. At the same time, the rotary movement ofthe turret is beginning, and the roller 25 which has been raised by thepush rod 93 moves on to the high portion of the cam to hold the shapingmeans tightly about the form which, in the meantime, through the mediumof contact with the commutator as the turret rotates, is heated. As soonas the turret has rotated a distance sufcient to bring another unit tothe operator with its roll dropping into the notch'la, rotary movementof the turret stops, due to release of the arm 89 from the notched cam62. The cam 1-8 however, is maintaining the first form in clamping andpressing relation to the shoe. x i 1 The operations are thenrepeateduntil every unit has been filled, whereupon the rst unit'will havereached the operator and theshoe element thereon will be ready forremoval.

Although a turret capable of carrying twelve forms is illustrated in thepreferred'embodiment, it will be obvious that any desired number ofunits may be provided, to suity conditions in an individual shoefactory.

As described, the cam 1, and the operating connections are arranged tocontinuously compress the shaping wings about the constantly heatedforms, with the exception of the one unit which is positioned in frontof the operator.

This is perfectly satisfactory so long as shoe elements are in place onthe forms, but conditions may arise where it will be unnecessary toutilize all of the units on the machine, and this will result inclamping wings of an unused unit directly against a heated form, withoutthe relief afforded by placement of shoe elements thereon,

-a condition which tends towards injury of the contact liner and rubberpad, by the constant heat.

To avoid such a condition, means may be provided to render a selected'unit, or units, inoperative, as illustrated in Figs, 14 and 15.

In the embodiment of these figures, the rocker 24 is replaced by a yoke2|, and the rod 21, cross head 28, spring 30 and links 33 are omitted infavor of a frame 22, connected to the pivot pins 41. Extending from theframe is a finger 3| which is suitably notched to detachably engage across bar 32, carried by the outer ends of the yoke 2|.

The cross bar 32 is mounted in the yoke for yielding movement, beingheld in position by springs 2|a, for the purpose of facilitatingengagement or disengagement between the finger 3| and the bar 32.

This arrangement, with the yieldable cross bar 32 and a substantiallycentrally located ringer 3| will permit the wings to secure their ownpositions, or equalize pressures just as in the arrangement utilizing across head 28 and rod 21.

Should it be desired to operate the machine by hand power instead of bythe automatic application of mechanical or electrical power, themechanism within the column and in the base portion thereof may bedispensed with, and individual unit actuating mechanism, such asdisclosed in the aforesaid Patent No. 1,720,891, may be substitutedtherefor. All that is necessary in this connection would be to secureeach of such actuating mechanisms to the lower portion of the Wings 9,and to connect same to the rod 21 at the point 26. Inasmuch as this handactuating mechanism carries a locking mechanism with each unit thereof,it is unnecessary to utilize the rocker arm 24 and the cam mechanism 18. The bracket 58, by its engagement with the lug which supports theadjusting screw 55 will still function to limit upward movement of thehead 34.

As stated above, the entire unit, including the forming and pressingmeans, `of said patent might be substituted if hand operation is founddesirable. i

The operation by hand is otherwise the same as in the power machineexcept, of course, that the turret will be moved step by step manuallyand the pressing Wings and straps clamped against a shoe manually by theactuating mechanism, not shown, but fully described and disclosed in thesaid patent, and to which reference may be found desirable.
